Hello, friend.

Lucy Li


I'm a Stanford student, studying artificial intelligence as well as human minds, behavior, and language. I'm mainly centered around natural language processing (NLP), but also exploring related fields. I'm a fifth and final year coterm, with a B.S. in Symbolic Systems (≈ cognitive science) and soon a M.S. in Computer Science.

My research aims to better understand people's interactions with each other. Last summer, I was a Summer@EPFL student in the Data Science Lab with professor Robert West. I've also worked with the Stanford SNAP Group, mentored by University of Michigan professor David Jurgens. I've been lucky to receive small grants for conference travel and crowdsourcing from SymSys and Stanford Undergraduate Research and Advising.

I'm very involved with Stanford's SymSys Program. I am a two-time vice president of the student society and I'll be advising students again during Winter and Spring 2019. I'm also passionate about education, especially when it comes to increasing diversity in science, technology, engineering, and math (STEM). Check out this blog series I made on teaching NLP.

Papers

I publish under the name L. Lucy.

Using sentiment induction to understand variation in gendered online communities.
Li Lucy, Julia Mendelsohn.
SCiL 2019.
We examine gender as a social variable on Reddit, and how community-specific sentiment can be a useful indicator of social meaning. Link.


Are distributional representations ready for the real world? Evaluating word vectors for grounded perceptual meaning.
Li Lucy, Jon Gauthier.
RoboNLP @ ACL 2017.
Widely-used word embeddings such as GloVe and word2vec may be deficient for predicting some types of meaning. Link.

Projects

Here are some of my course projects:

Campaign Funding Under Uncertainty
Sawyer Birnbaum, Lucy Li, Vivian Hsu
We define the problem of efficiently donating money as a POMDP. Link.


Speakers choose shorter words in predictive contexts
Lucy Li
I replicated the multiple-choice sentence completion experiment of Mahowald et al. (2013). Link.


Paying Attention to SQuAD: Exploring Bidirectional Attention Flow
Heather Blundell, Lucy Li
This reimplementation of BiDAF was pretty close to the original paper: 76.037 F1 and 66.663 EM. Link.


Giving Gold: Understanding Appreciation in Reddit Communities
Julia Mendelsohn, Lucy Li
We investigated gilding behavior across subreddits. Link



Historical and Modern Image-to-Image Translation with Generative Adversarial Networks
Vinson Luo, Michael Straka, Lucy Li
We used CycleGANs to colorize historical images. Link.


The Effect of Speech Disfluencies on Turn-Taking
Lucy Li, Kartik Sawhney, Divya Saini
We predicted end-of-turns in spoken conversations using filler words and discourse markers. Link.


A Resource Rational Analysis of Memory Use in Bayesian Updating
Lucy Li, George Pakapol Supaniratisai, Stephanie Zhang
We built a hierarchical Bayesian model of memory, where noise-less memories are costly. Link.


DominAI: An AI Player for Dominoes
Guillermo Angeris, Lucy Li
We created an agent using game playing and sampling algorithms to beat opponents at four-player dominoes. Link.

Other

I love food so much that I've been Yelp Elite for two years.

I also design Snapchat geofilters, which have over 26 million views worldwide.

Before college, I interned on the production team for the Emmy-award-winning PBS Kids show, SciGirls.
